The most accurate sights I have ever used on a handgun were the haley strategic thirteen sights, the rear notch and front blade are both .125 - with that being said, it was unforgiving if your indexing was off, however super fast and accurate when done correctly. I am wondering if you know of any .215 height front sights that are .125 width with a pro glo style front - I feel that would be a superb combination. I have transitioned to mainly RDS equipped handguns, but I am able to almost match my accuracy at distance with the haley sights.
